ἀπό governs the genitive case. As is the case with most Greek prepositions, ἀπό is a versatile word which can take the idiom of a number of English words. To further complicate matters, in Koine Greek, the distinctions between various prepositions are often blurred, leading to ἀπό fulfilling functions classically reserved for words such as ἐκ, ὑπό, and παρά.
